Note to criminals: If you're trying to shield illegal activity, tinting your car windows dark may not work out so well.

Milwaukee police recently arrested two men after a routine traffic stop to check for overly dark windows led to the discovery of significant amounts of drugs and several guns — despite one man's Florida concealed carry permit.

According to a criminal complaint:

Officers Martez Ball and Omarlo Phillips were patrolling in the area of N. 35th St. and Courtland Ave. about 5:30 p.m. on Tuesday when they noticed a black Pontiac Grand Prix with extra-dark windows. The officers stopped the Pontiac to check the window tint level.

When the four people inside lowered the windows, police first noticed none of the occupants were wearing seat belts. When asked if anyone was armed, Joshua J. Berry, 32, showed a Florida permit to carry a concealed weapon.

Wisconsin recognizes many other states' permits, but Berry also had an outstanding municipal warrant, so he was arrested. He was carrying a .45-caliber semiautomatic handgun.

The other rear-seat passenger, Christopher J. Berry, 31, told police he was on probation. He was carrying $27,727. Because riding with someone who had a gun was a violation of his probation, he too was arrested and probation officials authorized a search of his home in the 5100 block of W. Keefe Ave.

There, police found another $7,200, inside a shaving kit hidden in a basement ceiling panel, marijuana, cocaine and more guns — three handguns, one with a 30-round magazine — and .22-caliber assault-style rifle, blank prescription pad and "a large quantity" of counterfeited prescriptions for oxycodone.

Christopher J. Berry is charged with possession of a firearm by a felon, and keeping a drug house, as party to a crime, while using a dangerous weapon.

Joshua J. Berry is charged with possession with intent to deliver marijuana and cocaine, and possessing a firearm as a felon.
